Shameless self plug: https://github.com/hoeck/schirm https://github.com/hoeck/schirm. It does exactly that, rendering arbitary html (inside iframes) between lines of a vt100 compatible terminal emulator, using escape-sequences to denote document data and images. Works quite well as a proof of concept. What annoys me so far is that its relatively slow (running find on a large dir may take ~20 times longer than on gnome-terminal) and the headaches around (automatically) resizing iframes.
